write equations for the horizontal and vertical lines passing through the point (-1,-9).

can someone explain this

:)

Horizontal line has a slope of zero because does not rise vertically.

The form that we have to use in this case is y=b because the slope is zero.

So I would say that the answer for this one is

Y=-1

And a vertical line has a undefined slope because it will go up infinitely.

And in this one we have to put the x-intercept.

So I would say that the answer for this one is x=-9

I hope you get it right :D
